nit: Maybe format it differently, so that it doesn't look like a list of two
items? E.g. "Adding extension <name> (<id>)" or something like that.

I got rid of this change; it's useful for my debugging but may not be something
that the extension team wants.

   bool is_extension_upgrade = false;
   bool is_extension_loaded = false;
   const Extension* old = GetInstalledExtension(extension->id());
   if (old) {
     is_extension_loaded = true;
     int version_compare_result =
         extension->version()->CompareTo(*(old->version()));
     is_extension_upgrade = version_compare_result > 0;
     // Other than for unpacked extensions, CrxInstaller should have guaranteed
     // that we aren't downgrading.
